Independent calculation and construction of a fence from corrugated sheets. Criteria for choosing metal posts for corrugated fences

Fence posts, according to experts, should be metal. They have many advantages:

• Increased strength;
• Rigidity;
• Long service life;
• Lack of special care;
• Beautiful appearance.

All these properties are very important when choosing fence posts.

This is what they look like fence posts 60 x 60 metal

They must be taken into account when choosing supports for the future fence. In most cases, a profile pipe of different sections is used:

• 80 x 80;
• 60 x 60.

Choosing a pitch between pillars

The optimal distance between fence posts is 2.5 meters. This makes it possible to accurately align horizontal logs when their length reaches three meters. Usually everything. In principle, you can do without painting work. In this matter, the financial condition of the owner of the fence plays a major role.

The standard height does not exceed three meters. From practical experience it is known that the best pipes for fastening fence sections made of wood different materials are profile metal pipes with a cross section of 60x60. Of course, you can install pipes of a different diameter, but the size 60x60 is considered optimal solution, since some fences may have a large windage, for example.

Profile pipe

Dimensions and characteristics of pillars 60 x 60

In order to have more reliable and very durable fence posts, it is best to mount posts with a profile section, with dimensions of at least 60x60 mm.

The price of such a pole does not exceed the cost of a round pipe, however, the appearance of such a support looks much better. When installing, 60x60 profile posts are much more convenient; it is easy to attach additional parts, as well as fences, to them.

To reduce the price, you can install used 60x60 pipes. The service life of such pipes is quite long, and the strength is no lower than that of new products. Such pipes can be welded to. They are easily attached to:

• Profiled sheeting;

IN last years Corrugated sheeting has become very popular for fencing, in which posts made of a 60 x 60 mm profile are installed.

This is what a corrugated fence with posts 60 by 60 mm looks like

The reasons for this popularity were:

• Availability;
• Easy installation;
• Speed ​​of work;
• Appearance;
• Long-term operation.

Sales of pipes for fencing

When determining the price, the following are taken into account:

• Wall thickness;
• Diameter;
• Length.

The most popular is the pipe, the length of which reaches three meters with a wall thickness of 5 mm. In this case, the pipe diameter can reach 150 mm. You can purchase such poles in online stores, as well as on the construction market.

Square pillars

Of course, the support pillars can be installed by yourself. different shapes and various sizes. However, square-section metal supports are very popular among individuals.

Advantages

• Such a pipe practically does not bend;
• It is very easy to attach any parts to it. It is much easier to attach logs and intake sections to a profile metal pipe than to a round pipe;
• Easy to transport for future installation. They are easy to transport on any cargo transport;
• Beautiful design, matching modern style. A square pipe gives the fence a respectable look;
• Versatility. Posts with a square cross-section can be used for any type of fence. They look great with a variety of materials:
  • Profiled sheeting;
  • Chain-link mesh;
  • Forged parts.

These are designed for long term operation. This is especially true for galvanized poles.
In principle, ordinary profile pillars will stand long years, if they are coated with an anti-corrosion compound and covered with special caps on top. This detail will protect the support from moisture getting inside the pipe. As a result, service life support pillars will increase several times.

Manufacturing

To obtain a square profile, for example, 60x60 mm, a round pipe is compressed. To do this, it is rolled through the rolls of a rolling mill. In production, the formation of such products is also carried out from several sections of pipe, which are welded together. Of course, this method has lower labor intensity, so the price finished products is greatly reduced.

Of course, supports made by rolling method cost much more than welded posts. They also differ in increased strength. In this case, each fence owner himself chooses the material suitable for him.

Pipe dimensions

When the question arises about the size of the future pillar, the following must be taken into account:

• Height;

If you need to fence off an area two meters long, a pipe of 60 x 60 mm and a wall of 3 mm will be sufficient. The round support should have a diameter of 60 mm with a three-millimeter wall. When installed, steel supports must be immersed in ordinary soil to a depth of more than 1.2 meters. If the soil is dense, the size of the recess should reach a maximum of 90 cm.

The pitch of the pillars is also important. The best value is considered to be 2.5 meters. When a fence is installed in areas strong winds, the step size decreases and becomes equal to two meters.

Unlike the European type of house construction, Russians like to enclose their houses with fences, the higher the better. There are several design options, the most popular, and also inexpensive, are designs made from metal pipes and profiled sheet.

Wooden structures are short-lived average term service life is 10 years, since a tree dug into the ground, even treated by special means, rots quickly. Concrete is more reliable, but installing purlins is much more difficult. Reinforced poles are not easy to drill, and not all builders can make embeds on them.

Metal pipes are quite expensive, which often stops customers. It is important to consider the service life, it is much longer. The metals that serve as the basis for the future frame are strong, durable, and easy to work with. Almost any material is attached to the frame: mesh, asbestos-bonded, cement-bonded sheets, cellular polycarbonate, wood, corrugated steel sheet. Structures last about 50 years, the lifespan of wood is 3-4 times less. A fence is a combined structure, there are several types:

1. Fences covered with corrugated sheets, are distinguished by their lightweight design. They are quite durable, although under the influence of a certain force, noticeable dents or, less often, holes appear. The metal of the profiled sheet is quite thin, complemented by a metal base; it is considered the most popular type of frame.
2. Chainlink– two types of mesh: metal, polymer. During installation, holes are drilled and the mesh is secured to the frame through them. These species are more common among construction sites; they often fence empty areas. Due to good review unpopular as permanent fencing.
3. Wooden fences popular due to their environmental friendliness and relative cheapness. Significantly different from metal bending, the process of wood processing is simpler and less expensive.
4. Gates assembled forged elements , require thicker pipes, forging weighs a lot. The profiles are unlikely to completely block the view; there will be empty space between the openwork elements. Due to their high cost, they are often used in conjunction with brick pillars.

Which pipe to make a fence from: basic parameters

Each metal base has its own set of specific characteristics to make it suitable, sometimes unsuitable, for use on a particular object. When choosing, you need to consider the following parameters:

• Material. What kind of steel forms the structure plays an important role. Galvanized steel is the most reliable, also expensive option. Black steel is used less, but is financially acceptable. The products require annual painting and removal of rust at the base.
• Diameter. The stability of the structure is directly related to the cross-section diameter. Strong winds can cause a fence held together by thin posts to fall. At a height of about 2 meters would be better suited square 80x80mm, or round 60mm. Minimum wall thickness 3mm.
• Height. Fences that are too high are sometimes called “sails”; they are the ones that have to hold back strong winds. When installing them, it is important to take into account the length, comparing it with the quality of the soil. Sometimes the soil is wet, loose, loose, and you have to increase the length to at least 15 cm. When it is not possible to independently determine the type of soil, you should contact a specialist.

Metal pipes due to more easy installation more popular than other materials. Assuming to give the fence a serious load, they are the ones who are able to withstand the gravity of the load being held, weather conditions. Among the obvious advantages of these structures, builders highlight the following:

Large types are installed only when using metal poles.

Can be used by manufacturers of frames for decorative purposes; the steel lends itself very well to painting.
Metal supports are reused many times. The fence project will be cheaper; you can make the frame using used pipes.

Calculation of the number of fence posts

The number of metal pipes cannot be neglected for the sake of reducing operating time, labor costs or cost. When the horizontal purlins do not fit together clearly, the entire rack looks unreliable; it is better to redo it. The number of supporting floors determines the reliability of the structure; it requires stiffeners. You can calculate it using a special formula: divide the area of ​​the site according to the distances between the supports, including the calculation of the cross-section. Profile views The allotted distance is usually 2 - 3 m, for round ones - 2-2.5 m. The heavier the structure, the smaller the distance between the supports. The lightest fences - mesh, corrugated sheets - imply a distance of 4-6 meters.

Which type is better

There are two main types: round, profile. Each type is good in its own way, but there are some differences:

• Section of round supports at minimum costs the material is more durable. There are thinner ones, they can still withstand considerable loads, and can be easily screwed into soft soil with a collar.
• Rectangular purlins It is more convenient to install to profile pipes. Due to the flat surface of the contact edges, welding takes place better, forming a more durable structure. They are easier to cut, which significantly reduces working hours.

What is the optimal pipe thickness for a fence?

Important role The correctness of the calculations is influenced by the height, distance between the posts, speed of wind gusts, and the type of main material of the fence. So, for example, a distance of 2 meters between the corrugated frame racks is suitable profile stand cross section 80x80, wall thickness 3mm.

For a round base, a diameter of 60mm with a wall of 3mm is sufficient. You can dig in supports of these parameters without a foundation, but you will have to deepen them to almost a meter when the soil is loose, 80 centimeters is dense (for a fence 2 meters).

Small fences about 1.5 meters high are supported on frames profile pipes section 60x60, thickness 2mm, round parameters 40x40, 2mm thickness.

Features of installation of pipes for fencing

The process is almost identical to the installation of all load-bearing structures. Digging is not a difficult task, the preparation of sections takes place without the participation of a team of builders, the task is quite within the power of two workers. It takes place in stages, so in order to carry out all the work correctly, you need to:

1. Mark the area where the fence is to be installed. Driven wooden pegs are connected to each other with a well-tensioned thread. You will get identical straight lines. You need to make sure that all the pegs are straight, otherwise the supports will also be driven in crookedly, which means either the frame will turn out uneven or the structure will have to be dismantled.
2. The number of pegs should be equal to the number of posts. That is, it is necessary to make calculations so that when replacing wooden temporary blanks with permanent metal ones, the fence will hold tightly.
3. In place of the pegs, a recess is dug for future pillars. It is more convenient to do this with a hand drill, experienced builders make do with a simple shovel. The quality of the soil plays a very important role: the softer the soil, the easier it is to work.
4. There are two options for installing a pole. First, it is simply placed in a hole, compacted with soil. The stand will hold much stronger if you fill the hole with sand, then pour it with water, then add more sand, it is better to additionally cement it.
5. First, the outer pillars are installed. A thread is stretched from pillar to post, thanks to which the rest are fixed. This makes it easier to make the frame more even, because the thread should lie on top at one level.
6. The pipe must be strictly vertical and level. When organizing these measurements, they use a special building level. Around the concreted rack they build reliable wooden supports- spacers, it will harden evenly and last longer.
7. Having placed the tables vertically and evenly, from above to below, the hole is filled with medium-sized crushed stone. It additionally fixes, especially a very important component when the soil is soft or clayey. After compaction, the crushed stone is covered with round-grain sand and finally bitonized. The heavier the fence, the more crushed stone will be needed to stabilize it.
8. Logs that are welded strictly horizontally are mounted only after cement mortar completely frozen. After the welding seams have cooled (except of stainless steel), goes through the final stage - an anti-corrosion primer is applied, although this is not necessary, then painted. Sometimes a canopy is installed at the top of the pipe, then precipitation, dust, and insects do not get inside.

The durability of the fence is directly related to how correctly the frame material is chosen. Metal supports are quite easy to install, easy to maintain, and last a long time. Comparing other types, one can highlight versatility and durability. It is a mistake to confuse support pipes with other rolled metal products for water supply or gas. All frames are manufactured in accordance with GOST standards.

The pricing policy is varied. The type of metal used by the manufacturer plays an important role. Steel is different and varied, price policy, section thickness, material strength are also different. Also important point is the cross-section itself, the wider the pipe, the more metal. And, finally, the determining factor most often is the novelty of the supports, because used ones are much cheaper. When making a second hand purchase, it is important to evaluate the appearance, especially the part that has been buried. Small rust can be easily removed with sandpaper on your own, but if the metal has begun to rot, it is better to avoid such a product. In a word, when making a permanent fence enclosing a site, you should not save money.

The reliability of the entire fence structure directly depends on the material of the supporting frame.

Install wooden posts, and the fence on your site will last no more than 10 years. Wood, even antiseptic, is susceptible to rotting.

Concrete is a more reliable option. But when installing such a structure, difficulties arise with fastening the purlins.

Drilling a reinforced pole is not easy, and not all developers can install embedded parts in it efficiently.

The best foundation is metal pipes for the fence– durable, easy to install and durable. On metal frame You can easily secure any fencing material - wood, profiled steel sheet, mesh, cellular polycarbonate, asbestos or cement bonded particle boards.

Budget developers are often stopped by the high price of metal. However, comparing the service life metal fence with wood, you will see the opposite.

Metal posts and veins will last at least 50 years while wooden frame During this period you will have to replace the fence 3-4 times with all the associated costs.

Profile or round pipe for the fence. What to choose?

From the point of view of science that studies the resistance of materials (resistance), the most advantageous is the circular cross-section of the pipe. With a minimum of material it provides maximum rigidity.

If we take into account the ease of installation, then round pipes inferior to the profile ones. Rectangular posts and purlins are more convenient to cut and join by welding. A flat contact surface allows all elements of the fence to be fixed more tightly and rigidly than a round one.

As we have already said, a round pipe with the same weight is stronger than a profile pipe in bending. Therefore, if you decide to buy round fence posts, you will save by reducing the weight of the metal. In addition, it is more convenient to install a round pipe in soft soil by screwing it in using a collar.

What pipe sizes should I choose for racks and purlins?

It all depends on the height of the fence, the type facing material, strut pitch and wind force.

If the fence of the site is within 1.8 - 2.2 meters, then the profile pipe for the fence made of corrugated board should have a cross-section of 80x80 mm (wall thickness 3 mm).

If a round pipe is used, then a diameter of 60 mm (3 mm wall) will be sufficient. With a fence without a foundation, metal posts will have to be buried at least 1.2 meters into soft soil, and 80-90 cm into dense soil.

The pitch of the fence posts is of great importance. Optimal - 2.5 meters. In areas with strong gusty winds, it should be reduced to 2 meters.

For low fences (less than 1.5 meters) can be used square pipe 40x40x2 mm or 60x60x2 mm with veins with a section of 30x20x2 mm or 40x20x2 mm.

Approximate prices for pipes of different sizes

Range of rolled metal products and choice of manufacturers steel pipes today is very wide. Therefore, before preparing material for the fence frame, you should familiarize yourself with market prices and estimate the optimal budget for the future fencing.

The most convenient for frame calculations are prices for pipes, calculated per linear meter of length, and not per ton. Having determined the total footage of fence posts and veins, you can easily calculate their cost.

Rectangular metal pipes for fence posts cross section 40x60 mm and a 2 mm wall are sold for 110-120 rubles per 1 rm. For a more powerful fence, you will need racks with a cross section of 80x80 mm (wall 3 mm). They can be purchased at a price of 260 – 290 rubles/rm.

A profile square pipe with sides 100x100 mm and a wall thickness of 3 mm is offered on the market at prices starting from 360 rubles/rm.

The size of the veins (purlins) to which the corrugated sheet is attached is always less than the cross-section of the pillars. The main task of these structures is to distribute the weight of the cladding and transfer it to the vertical posts.

When designing a fence made of corrugated sheets up to 2 meters high, a 40x20 mm tubular profile (2 mm wall) is most often used as purlins. Its average cost, depending on the sales region, ranges from 66 to 74 rubles. for 1 pm.

For higher and loaded fences, purlins from a pipe with a cross section of 60x30 mm (wall 2-2.5 mm) are used. Their purchase will cost from 95 rubles per 1 linear meter of profile.

For round steel electric welded pipes, the average cost is linear meter is this:

• 51 mm (wall 3) – from 136 rubles;
• 57 mm (wall 3 mm) – from 143 rubles;
• 60x3 mm – from 160 rubles;
• 76x3 mm – from 195 rubles;
• 89x3 mm – 242 rub.;
• 102x3 mm – 276 rub.

Features of installing a fence frame

Having decided which pipes are best to use for the fence and making a sketch of the connecting points, you can begin installation. At the same time, we must remember that the main enemies of the continuous metal fence– wind and soil. Therefore, it is best to embed stand pipes in monolithic concrete, even in the most economical “pit” way.

Simple driving or screwing of pipes into the ground for high fence- Not the best option. Unstable soil gets wet, dries out, and freezes. As a result, the fence frame may become warped or tilted. A concrete “anchor” will prevent the fence of the site from losing stability or changing its geometric shape.

The profile pipe used for the racks must be turned with its wide side perpendicular to the cladding. This will maximize the rigidity of the posts in relation to the wind, which tends to bend the wide “sail” of the fence.

Fastening the corrugated sheet with bolts to the 40x20 profile pipe

Unlike a continuous fence made of corrugated sheets, installing a frame made of pipes for a fence made of steel mesh chain-link is less responsible. This design is not even scary hurricane wind, because the mesh does not create much aerodynamic drag.

Here main task is to ensure the stability of the base, therefore sufficient penetration into the ground and concreting of the pillars are mandatory conditions for the stability of the entire structure.

The construction of a fence from corrugated sheets has some features associated with the low weight of the structure, which is subject to significant lateral loads from the wind. Due to incorrectly selected materials, the fence can quickly become loose in the wind, and steel sheets bend over. Therefore, before building such fences with your own hands, you need to figure out which pillars should be used and how to install them correctly so that the structure stands for a long time and does not become loose.

Perhaps the most practical option- ready-made factory poles made of metal pipes with already welded brackets for the veins

Pros and cons of structures made from corrugated sheets

To understand the nuances of installing such a fence, you should evaluate its advantages and disadvantages. The advantages are as follows:

• profiled steel sheets with colored polymer coating (usually polyester) look great on any type of fence and in combination with different materials;
• wide choose ;
• lightness and strength of the structure;
• simplicity and speed of fastening sheets, done with your own hands without the help of hired workers;
• affordable construction costs;
• long service life (about 20 years).

The disadvantage of a fence is burnout polymer coating, causing the surface to become dull and inexpressive. Therefore, when choosing pipes and corrugated sheets for a fence, homeowners are more inclined to dark colors, whose burnout is not so noticeable.

The lightness of the structure is also a disadvantage of the fence. It is well known that a light and large sail can carry a significant mass due to the force of the wind. A solid fence made of corrugated sheets is the same as a sail and it must be securely anchored in the ground on poles. Do not forget about the depth of soil freezing.

Support Structure Options

To build continuous fences from corrugated sheets with your own hands in private housing construction, it is customary to use the following types supports:

• metal racks made of round or profile pipes, other rolled metal;
• massive brick pillars on iron concrete foundations;
• wooden posts;
• supporting elements made of asbestos-cement pipes.

The most popular designs are made from various rolled metal products, but most often round and round pipes are installed. rectangular section. This best option in terms of construction cost/design reliability ratio. Only wooden racks will be cheaper, but they are not as durable and need protection from weather conditions.

The best way to hold the sail is to increase the massiveness of the structure, which is achieved by installing brick pillars with steel pipes embedded inside them. Besides high reliability and durability, such fencing is aesthetically pleasing appearance. There is only one drawback - the high cost of construction. Less commonly implemented is the option of using asbestos-cement pipes installed on concrete foundations. To choose the right solution, it is worth examining all the options in more detail.

Selection of metal supports

For the installation of a fence covered with corrugated sheets, the following types of rolled metal are suitable:

• round steel pipe, ;
• metal pipes of rectangular and square section;
• equal and unequal angles;
• channels, I-beams and even rails.

Given the high windage of the fence, fairly rigid elements should be used as supports, firmly embedded in the ground with your own hands. With a fence height of up to 200 cm and an installation step of 2 m, round pipes are needed, whose outside diameter is no less than 76 mm with a minimum wall thickness of 2 mm, and better - 3 mm. Their length is selected depending on the depth of immersion in the soil and under normal conditions is at least 3 m (2 m above the ground and 1/3 in the ground).

Normal conditions mean ordinary sandy soil or loam not subject to frost. In the latter case, they are extended in such a way as to pass the entire freezing layer of soil and drop 0.5 m below this boundary.

Nuances of metal supports

If the height of the fence exceeds 200 cm or the span increases to 2.5-3 m, then the diameter of the pipes will be larger. For a standard span of 2.5 m with a height of 200 cm, you should take supports with an outer diameter of 89 mm and a wall thickness of 3 mm. To securely secure a section 250 cm high and 3 m long, you will need even more powerful racks - at least 108 mm.

In recent years, supports made of rectangular pipes have become increasingly used. For a standard span of 200 cm x 2.5 m, it is customary to use a 60x60 mm square pipe with a wall thickness of 3 mm, although some homeowners install thinner-walled products at their own risk. If you are building a fence with your own hands on the side of a vacant lot or other open space With strong winds, then it is appropriate to take elements of a rectangular section of 80x40 mm. At the same time, the smaller size (in in this case 40 mm) must be turned towards the vacant lot in order to ensure the rigidity of the structure.

Racks made from corners or channels may not look as aesthetically pleasing, but with the right approach they will not be inferior in reliability. Equal angle corners can be installed single on a standard section if their size is at least 80x80 mm with a wall thickness of 6 mm. Products with a shelf width of 56-75 mm are welded in a “box” to obtain full-fledged fence posts. It’s the same with channels - you can install an 18 cm wide element alone, and cook “boxes” from smaller ones.

About brick pillars

Installing a respectable fence with and filling the openings with corrugated sheets is a rather labor-intensive task and will not be cheap. Although you can save money by doing the work yourself. But by building brick pillars, you won’t have to worry about them being knocked over by the wind.

The following types of bricks are suitable for construction:

• ceramic solid or hollow;
• silicate white or colored;
• special facing.

A steel profile pipe is placed inside the brick rack as a stiffening element, and then transverse joists and the corrugated sheet itself are attached to it. Her maximum size, which can only be inserted inside the pillar, equal to half brick and is 120x120 mm. But so big sizes pipes are needed in the places where the gates are hung, and to fasten the spans it is enough to take 60x60 mm products. Steel strips for installing corrugated sheets should be welded to them, and the opening between the brickwork and the walls of the pipes should be filled with mortar.

The construction of brick pillars is carried out on reinforced concrete foundations columnar type. To do this, you will have to dig holes with your own hands to the freezing depth, hammer profile pipes into them and concrete them using reinforcement cage. Afterwards, the steel core is covered with brick to a thickness of 120 cm. The length of the rack is selected so that its top is level with the cut brickwork. To protect against precipitation, decorative canopies made of painted metal or concrete should be installed on the fence supports.

Application of wooden racks

The reliability of the supporting part of the fence can be ensured by a beam with a cross-section of at least 10x10 cm or a rounded log with a diameter of 12-15 cm. The best types of wood are pine, larch or spruce, pre-treated with an antiseptic composition. The height of the pillars is selected depending on the installation method.

Wooden posts for corrugated fencing can be installed in two ways:

1. Concreting or backfilling the supports in the pits, having previously treated underground part bitumen mastic.
2. Make the underground part of the racks metal by concreting sections of profile pipes with your own hands, and then attaching wooden posts to them.

Installation of a wooden fence covered with corrugated sheets is simple and, most importantly, inexpensive. Wooden crossbars are nailed between the posts, and sheets of corrugated sheets are screwed to them on the front side with self-tapping screws. From the outside, the fence looks like a solid metal barrier, no wooden parts can not see.

Asbestos cement supports

In this case, the reliability of the supporting part is facilitated by the decent weight of asbestos-cement pipes, which, upon completion of installation, are filled from the inside with concrete. Thanks to this, the height of the fence with asbestos cement posts can be easily increased to 3 m. The structure is quite heavy, and therefore must rest on a columnar or strip foundation.

As in the option with brick pillars, racks made of asbestos-cement pipes must be concreted in the ground to a depth of 0.8-1.5 m, depending on the height of the fence. For reliability and stability, anchoring is performed in the underground part of the supports - drilling through holes, into which pieces of periodic profile reinforcement are then inserted. When you pour the foundation of the fence with concrete, the reinforcement will firmly connect it to the post.

To install corrugated sheeting, you need to make holes in the pillars with your own hands, where you then insert bolts for fastening crossbars made of steel pipes measuring 40x40 mm. If the span reaches 3 m, then the profile will have to be taken larger. The corrugated sheet is screwed to the profiles with self-tapping screws or self-drilling screws.
